Abstract: | Peduncularistine, Triabunnine and Aristolarine, Three Ne Indole Alkaloids from Aristotelia peduncularis (LLABILL.) HOOK, F. Peduncularistine ( 1 ), triabunnine ( 2 ) and aristolarine ( 3 ), three new indole alkaloids, have been isolated from Aristotelia peduncularis (LABILL.) HOOK. F.; the structure and absolute configuration of 1 were elucidated on the basis of spectroscopic data and confirmed byt transformation of 1 into aristeserratine ( 4 ), a known alkaloid isolated from the same plant. The proposed structure 2 for the second alkaloid and its absolute configuration were established but spectroscopic means and by partial synthesis from 4 . The relative configuration of 3 was postulated on the basis of spectroscopic and biogenetic arguments. |
